So the EXUP valve on my bike when i got it was showing issues, 7K code at start, so cleaned it up and greased it all up, all is well now aside from a broken bolt ( not me! )
Reason i post is who runs without it, and what impact does it have...
I have read it kills performance and low down torque, yet i see after market exhausts from certain manufacturers that have no EXUP...
Would a dyno against a standard EXUP versus a set of pipes with no EXUP show big differences....
